SPOOL.

SPECIFICATION forming part Of Letters Patent No. 240,436, dated April19, 1881.

v Application filed February 1,1881. (Nomodel.)

To all whom it may concern Be it known that I, MARK W. MARsDEN, acitizen of theUnited States, residing at Connellsville, in the county ofFayette and State of Pennsylvania, have invented certain new and usefulImprovements in Spools 5 and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers-skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to an improvement in spools and bobbins forsewing-threads; and it consists in such spools and bobbins constructedof paper-pulp and asbestus compressed into the shape of a spool by meansof suitable dies, and in the dies A A, plungers B and B', cylinder G,guide D, and press-blocks E E, and in the combination and arrangement ofthe parts, as hereinafter more fully described.

In the drawings, Figure l is a plan View of my invention. Fig. 2 is alike View with section AJ removed. Fig. 3 is a vertical sectional view.`Fig. 4 is a detached view of section A'.

Fig. 5 is a detached view of plunger B'. Fig. 6 is a similar view ofplunger B, showing operation 5 and Fig. 7 is a view of a series of dies.A represents a die formed in sections, the parts aa being designed tomold the cylinder of the spool, and the more concave parts, b b, tostamp out the wheels thereof. The section A has cast solid therewith thepins d d, which are designed to fit, in practice, in the orifices e einsection A', to hold the sections rigidly together.

B is a plunger, rigidly secured to the side plate, f, and havingprovided therein the horizontal orifice a'.

The guide D has rigidly secured thereto or cast solid therewith theperforated cylinder O, and it is adjustably supported and guided by theguide-rods b' b. These guide-rods are secured to the Vplunger-plate f,and project through oritices provided in the guide, and are providedwith the heads e' e'.

The plungers B and B are actuated by compression applied to the blocks EE.

The pulp is inserted in the openings provided in the diesAA, and theplungers B and B' are then forced home by pressure applied to thepress-blocks E E, and as these dies are arranged together in plates,comprising a large series thereof, as shown, a large number of spoolsare thus formed at each successive operation thereof.

The perforated cylinder G is provided with the small transverse orificesshown, to prevent the escape of moisture from the pulp when undercompression, and thus. to avoid injury to the outside of the spool; andin practice it is withdrawn before the plungers are removed, to preventthe breaking or fracture of the edge of the central orifice of thespool.

In the process of constructing or stamping out the spools from pulp, asaforesaid, I employ a number of dies, as shown in Fig. 7, provided insuitable bed-plates, the plates being arranged to disconnectsectionally. K

The pulp may be colored, to obviate the necessity of staining orpainting the spools, or the spools may be colored in the manner whichordinarily obtains in their construction.

A gloss is produced uponthe spoolvby compression, similar to thatproduced by the process of calendering; and a small quantity of asbestusis also thoroughly intermingled with the pulp, to prevent combustionthereof, which cannot be accomplished with the wooden spool.

The name of the manufacturer, number of the thread, its color, quality,and the quantity contained on each spool are engraved or raised on eachdie or set of f dies for each spool, and thereby impressed on each spoolas manufactured.

My spool is designed to supersede the ordinary Wooden spool and bobbin,and will effect a great saving in material and labor, and therebygreatly economize the cost of thread products for domestic or otherpurposes.

What I claim, and desire to secure by Lety ters Patent, is-

1. The die A, formed in sections c c and concave parts b b, incombination with plungers B and B', substantially as shown anddescribed.

2. The plunger B, in combination With guide D, side plate, f, havingtherein the horizontal orifice a', and blocks E E, substantially asshown and described.

3. A spool or bobbn made of asbestus and In testimony whereof I affix mysignature in 1o pulp, to prevent combustion thereof, substaupresence oftWo Witnesses.

tially as'shown and described.

4. The plunger B, in combination with guide MARK WORSNOP MABSDEN.

5 D, perforated cylinder G, and die A, substantially as shown anddescribed. Witnesses:

5. The plunger B, in combination with guide B. F. FEAR, D and plungerB', substantially as shown, and WM. VANGE.

for the purpose described.
